This task is solved according to the invention by means of a device for the infusion by extraction of a capsule in portions with a first element of the infusion chamber and with a second element of the chamber of
infusion, in which the first infusion chamber element can be moved between a loading position, in which the first and second infusion chamber elements are spaced apart from one another for the introduction of the capsule in portions, and an extraction position, wherein the first and second infusion chamber elements have been approximated towards each other for the formation of a substantially closed infusion chamber for the capsule in portions, and wherein the infusion device it is designed in such a way that the alignment of the capsule in portions remains substantially constant as it is transferred from the loading position to the extraction position.
Therefore, more advantageously, an alignment of the capsule in portions during transfer from the loading position to the extraction position is not required, so that the danger of a blockage of the infusion device by virtue of a misalignment or totally absent. In particular, the portion capsule moves in translation during the transfer of the first infusion chamber member from the loading position to the extraction position only in the axial direction.
According to a preferred embodiment of the present invention it is provided that the infusion device present
a spacing means, which is provided for the spacing of the capsule in portions from the first infusion chamber element at least in the loading position. Advantageously, the capsule is prevented from tilting in the loading position or during transfer in the direction of the extraction position via the spacing means. The capsule in portions is held in position through the spacing means, until the infusion chamber is closed. For this purpose, the spacer means has a free end projecting spring-like in the direction of the second element of the infusion chamber. The spring-loaded resilient free end serves to prevent a part of the capsule from slipping in portions in the direction of the first element of the infusion chamber, so that the capsule in portions can not swing in the direction of the first chamber of infusion. The elastic spring configuration also serves to reduce the limits of the tolerance of the position of the capsule. The spacer means is configured in such a way that a lower area of the capsule in portions can not slide in the direction of the first element of the infusion chamber.
According to a preferred embodiment of the present invention, it is provided that the spacing means is
configured in one piece with a base plate fixed in the first element of the infusion chamber. The spacer means can therefore be mounted comparatively simply on the first element of the infusion chamber. In particular, the base plate has a mounting hole, for example for the realization of a fixing screw. The spacer means is especially designed as a bending spring made of metal.
According to a preferred embodiment of the present invention, it is provided that the base plate has at least one piercing tip projecting in the direction of the second element of the infusion chamber. Advantageously, the base plate serves both to retain the capsule in portions in a constant alignment through the spacing means, as well as to perforate the capsule in portions during the closing of the infusion chamber. Alternatively, it is provided that the infusion device has another base plate, which has at least one piercing tip projecting in the direction of the second element of the infusion chamber, in which the base plate is preferably arranged between the first element of the infusion chamber and the other base plate. Therefore, advantageously, an arrangement is made as compact and stable as possible in terms of the construction of the drilling means and the means
spacer Preferably, both the base plate and the other base plate have, respectively, a fixing hole, which overlap in the axial direction, so that the base plate and the other base plate can be fixed with a screw of common fixation in the first element of the infusion chamber. Preferably, the base plate or the other base plate has four piercing tips projecting in the direction of the second element of the infusion chamber, in which two first piercing tips are arranged in a common horizontal plane and in the that two second piercing tips are disposed in a common vertical plane, so that the vertical plane preferably extends in the center between the first two piercing tips. Advantageously, the first two piercing tips are disposed above the two second piercing tips, so that during the introduction of the extraction fluid the first two piercing tips can operate first as a ventilation hole for the capsule in portions.
According to a preferred embodiment of the present invention, it is provided that the base plate or the other base plate has a feeding orifice for the introduction of extraction liquid into the infusion chamber, in which the feeding orifice is preferably arranged in the vertical plane and / or in which
the feeding orifice is preferably arranged between the two second piercing tips and / or in which the feeding orifice comprises a semi-lateral recess configured in a marginal region of the base plate or of the other base plate. Advantageously, in the extraction position, the extraction liquid is introduced through the feeding orifice into the infusion chamber. In this case, the extraction liquid comes through the holes in a cap in the capsule in portions, which are generated during the closure of the infusion chamber through the piercing tips, to the inside of the capsule in portions .
According to a preferred embodiment of the present invention, it is provided that the first element of the infusion chamber has a lower holding means for retaining a lower marginal area of the capsule in portions, in which the spacing means is configured for spacing the capsule in portions from the first infusion chamber element in the region of the retaining means, wherein preferably the free end is disposed on one side of the base plate or the other base plate which is directed towards the retention medium. Advantageously, in this way the lower marginal area of the capsule in portions is prevented from slipping on the retaining means in the direction of the first chamber element.
infusion and in this way is carried out a tilting of the capsule in portions. Alternatively, it is provided that the spacing means is configured in the form of a notch, a groove and / or a recess in the support surface of the retaining means, to prevent a slippage of the capsule flange on the retaining means. in the direction of the first element of the infusion chamber. It is also conceivable that the retaining means is provided with a non-slip coating as spacer means.
According to a preferred embodiment of the present invention, provision is made for the infusion device to comprise lateral retention arms with retention surfaces directed towards the first infusion chamber element, wherein the spacing means is configured in such a way that in the loading position the spacing means, the spacing means presses the capsule in portions spring-elastic against the retaining surfaces. In particular, a tab of the capsule is pressed in portions against the retaining surfaces. By virtue of the asymmetric configuration of the capsule in portions, the capsule in portions tends to swing in the direction of the second infusion element. The lower marginal zone then slides against the first element of the infusion chamber. The retaining surfaces and the spacing medium now take care that in the loading position or
well during the transfer from the loading position to the extraction position the capsule in portions does not tilt in the direction of the second element of the infusion chamber, since the tab of the capsule in portions rests on the retaining surfaces and the Half spacer prevents slipping of the lower portion of the capsule in portions in the direction of the first infusion chamber element. Preferably, the spacing means is configured in such a way that the spacing means approaches in the extraction position the first element of the infusion chamber, so that the extraction process and the tightness of the infusion chamber in the position of Extraction is not impaired through the spacing medium.
Another object of the present invention is a method for operating an infusion device, in particular according to the invention, wherein in a first stage of the process a capsule is inserted in portions between the first and second chamber elements of infusion and in which in a second subsequent step of the process the first element of the infusion chamber is moved from the loading position to the extraction position, in which the alignment of the capsule in portions is kept constant during the second stage of the procedure. Advantageously, this prevents a capsule stop in portions in marginal areas of the capsule.
second element of the infusion chamber during the closing of the infusion chamber. Preferably, the portion capsule is maintained in a vertical alignment during the second stage of the process, i.e., that the plane of the main extension of a capsule cap in portions is aligned essentially parallel to the gravitational field or to the vertical field and preferably perpendicular to the axial direction.
According to a preferred embodiment of the present invention, it is provided that at the beginning of the second stage of the process the capsule is distanced in portions by means of a spring-elastic spacer means from the first element of the infusion chamber and in which At the end of the second stage of the process, the spacing means is pressed through the capsule in portions against the first element of the infusion chamber. Preferably, during the second stage of the process, the first element of the infusion chamber is first linearly displaced along an axial direction and then further pivoted about an axis of articulation perpendicular to the axial direction. The alignment of the capsule in portions remains constant also during the articulation of the first element of the infusion chamber. In this case, the spacing means is spring-loaded elastically against the first
element of the infusion chamber, so that the capsule in portions does not tilt. An articulation of the first element of the infusion chamber and shortly before the closure of the infusion chamber has the advantage that the piercing tips do not come into contact already in the loading position with the capsule in portions. In this way, the capsule in portions is prevented from remaining hanging during the introduction of the same in the piercing tips.
The invention is explained in detail below with the aid of exemplary embodiments represented in the figures. The figures only illustrate exemplary embodiments of the invention, which does not limit the essential idea of the invention.

The portioned capsule 2 comprises a truncated cone made of plastic and configured in the form of a cup. He
The truncated cone moves in a hermetic manner to the air by means of a cover of the capsule 13 made of plastic or aluminum foil. Within the portion capsule 2 there is a beverage substance, in particular a removable toasted powder coffee by means of an extraction liquid or an instant beverage or tea granule. Optionally, the portioned capsule 2 has a filter element, not shown, which is spaced from a bottom of the capsule 14 of the capsule in portions 2 and is arranged between the bottom of the capsule 14 and the beverage substance. The cover of the capsule 13 is glued or welded in the region of a flange of the capsule 15 with a truncated cone.
The first element of the infusion chamber 3 has, on an end surface 18 facing the second element of the infusion chamber 4, another base plate 9, which comprises four piercing tips 7. The four piercing tips 7 are spaced at the direction of the second element of the infusion chamber 4 from the other base plate 9. Two first piercing points 7 'of the four piercing tips 7 are disposed in a common horizontal plane 101, while two second piercing tips 7'. The four perforation tips 7 are arranged in a common vertical plane 102. The vertical plane 102 extends especially parallel to the gravitational field of the earth and in the center between the first two points of the earth.
7 'drilling. The two second piercing tips 7 '' are disposed below the horizontal plane 101. The other base plate 9 has a semi-lateral recess as a feed hole 8, which is disposed along the vertical plane 102 between the two second piercing points. 7 ''. The feed hole 8 is configured along the axial direction 100 in coincidence with a water outlet 16 configured in the first element of the infusion chamber 3, so that in the extraction place the extraction liquid can be conducted , in particular hot water, through the water outlet 16 and the feed hole 8 to the infusion chamber. During the closure of the infusion chamber, the cap of the capsule 13 is pierced through the piercing tips 7, so that the extracted extraction liquid reaches the interior of the perforation capsule 2 and interacts with the beverage substance. .
The first element of the infusion chamber 3 also has, on its underside, a rigid lower retaining means 10, and in particular a one-piece means with the first infusion chamber element 3, on which it rests in the loading position. and during the transfer of the first element of the infusion chamber 2 from the loading position to the extraction position the area of the flange of the capsule 15 which is directed downwards. In the
extraction position, the retention means 10 is arranged below the infusion chamber and below the second infusion chamber element 4. In addition, the first infusion chamber element 3 has two lateral retention arms 11, whose ends The free ones are directed towards each other and present, respectively, a retaining surface 12 directed towards the first element of the infusion chamber 3. The retaining arms 11 are provided to laterally cover the flange of the capsule 15 in the loading position and during the transfer of the first element of the infusion chamber 2 from the loading position to the extraction position, so that the capsule in portions 2 does not tilt in the direction of the second element of the infusion chamber 4.
The second element of the infusion chamber 4 has a second perforation means, comprising a puncture tip pointing in the direction of the first infusion chamber element 3 and which is arranged inside the hollow space and is preferably connected to the infusion chamber 3. through a detachable retaining closure with the second element of the infusion chamber 4. The puncture tip is provided with lateral grooves, which extend parallel to the axial direction 100. Preferably, the bottom of the capsule 14 is perforated during the closure of the infusion chamber or through the formation of pressure inside the
capsule in portions 2 through the puncture tip, so that the beverage generated in the extraction position through the interaction between the extraction liquid and the beverage substance can flow towards a place of cession of the beverage.
In FIG. 1, the first element of the infusion chamber 3 is illustrated in the loading position, that is to say that the first infusion chamber element 3 is spaced along the axial direction 100 from the second element of the infusion chamber 3. infusion chamber 4. In this starting position, the capsule in portions 2 is now introduced along a vertical loading direction 17 through a user not shown in an intermediate zone between the first and second chamber elements of the chamber. infusion 3, 4. A casing of the infusion device 1, configured as part of the second element of the infusion chamber 4 has for this purpose a feeding orifice, through which the capsule is inserted in portions 2. The first element of the infusion chamber 3 is tilted in this case in front of the second element of the infusion chamber 4 in such a way that the end surface 8 is inclined in front of the loading direction 17. Through e. In this inclination, the area of the first element of the infusion chamber 3 which is directed towards the feeding orifice is the one furthest from the second element of the infusion chamber 4,
so that the capsule in portions 2 can be inserted in the intermediate zone, without in this case threatening a hooking of the capsule in portions 2 with the piercing tips 7.
In figures 2 and 5 it is illustrated graphically that the capsule in portions 2 falls under the action of the force of gravity laterally in the area between the first and second infusion chamber elements 3, 4 and rests thereon on the medium of 10. At the same time, a tilting of the capsule in portions 2 in the direction of the second element of the infusion chamber 4 is prevented through the lateral retention arms 11, the flange of the capsule 15 being supported in the direction of the second element of the infusion chamber 4 on the retaining surfaces 12, so that the capsule in portions 2 is substantially axially aligned along the axial direction 100. The cap of the capsule 13 as well as the bottom of the capsule 14 they are aligned, therefore, essentially parallel to the load direction 17 or to the gravitational field and perpendicular to the axial direction 100. Due to the strong asymmetry of the capsule in portions
2 (the maximum weight of the capsule in portions 2 points hanging freely in the direction of the second element of the infusion chamber 4) a torque is caused on the capsule in portions 2. This torque can lead to the area bottom of the capsule in
portions 2 or else of the flange of the capsule 10 slides on the retaining means 10 in the direction of the first infusion chamber element 10. The capsule in portions 2 would then swing despite the fastening of the flange in the upper region of the capsule in portions 2 through the lateral retaining arms 11 in the direction of the second element of the infusion chamber 4. When a user next tried to close the infusion chamber, the capsule in portions 2 would hit its bottom of the capsule 14 possibly against a lower marginal zone 24 of the second infusion chamber element 4 and thus block a closure of the infusion chamber. So that the lower portion of the portion capsule 2 does not slide in the direction of the first element of the infusion chamber 3, the infusion device 1 has a spacing means 5, which distances the lower region of the capsule in portions 2 from the first element of the infusion chamber 3. In this way, the capsule in portions 2 remains in an alignment aligned axially along the axial direction 100. Both in the loading position and also during the transfer of the first element of the chamber of infusion 3 from the loading position to the extraction position, the alignment of the capsule in portions 2 remains constant. The portion capsule 2 remains especially aligned axially along the axial direction 100, of
so that a safe introduction of the capsule in portions 2 into the hollow space during closure of the infusion chamber can always be ensured.
In the present example, the spacing means 5 - as illustrated in figures 3, 4, 5 and 7 - comprises a metal bending spring 21, which is fixed on a base plate 6 in the first infusion chamber element 3 and has a free end 22 projecting in the lower area of the capsule in portions 2 in the direction of the second element of the infusion chamber 4, which can be moved in the spring-loaded extraction position on the end surface 18 of the first element of the infusion chamber 3. The free end 22 presses the lower area of the capsule in portions 2 in the direction of the second element of the infusion chamber 4, so as to prevent a slip in the direction of the first element of the infusion chamber 3. The base plate 6 is preferably arranged between the other base plate 9 and the first element of the infusion chamber 3, the base plate 6 having the other base plate 9 orifice 19 are aligned with each other, through which a common fixing screw for fixing the base plate 6 and the other base plate 9 to the first element of the infusion chamber 3 can be guided. the end surface 18 is preferably made with a cavity 20 in the shape of the
outer contour of the base plate 6 of the other base plate 9, so that the other base plate 9 and the base plate 6 are inserted into the cavity and the other base plate 9 ends flush with the end surface 18 remaining.
Alternatively, provision is made for the spacing means 5 to be configured in the form of a notch, a groove and / or a cavity in the bearing surface of the retaining means 10, pointing upwards, for the flange of the capsule 15, to prevent a slippage of the flange of the capsule 15 on the holding means 10 in the direction of the first element of the infusion chamber 3. It is also conceivable that the holding means 10 is provided with a non-slip coating as a holding means 5. .
Through the inclination of the first element of the infusion chamber 3, a contact between the piercing tips 7 and the cap of the capsule 13 is also avoided to a large extent in the face position. The holding means 10 optionally has on its free outer end a edge, which prevents an unwanted slippage of the tab of the capsule 15 from the holding means 10, that is to say, in the direction of the second element of the infusion chamber 4.
During the closing of the infusion chamber, the capsule in portions 1 remains in the axial alignment, so that at the end of the closing movement, the first element of
the infusion chamber 3 is pivoted in the same way to an axial alignment. However, the flange of the capsule 5 rests completely in the marginal region 24 of the second element of the infusion chamber 4, so that the axial alignment of the capsule in portions 2 is not altered. The spacer means 5 only approaches the first element of the infusion chamber 3 in a spring-elastic manner and the infusion chamber is hermetically sealed to start the extraction process. At the end of the extraction process, the first element of the infusion chamber 3 is moved back to the loading position shown in FIG. 1, so that the capsule in portions 2 consumed is displaced during the backward movement of the first delivery element. the infusion chamber 3 by means of an expulsion element 23 out of holding means 10 and falling downwards.
